The difference between printing and printing is that
1, printing (especially color printing) uses water-based ink, while printing uses oily ink;
2. Color printing pictures show the fineness of printed photos according to the distribution of ink dots in the printer, while printing presents images through the distribution of ink dots, which has different manifestations;
3. Printing is usually limited to a small amount of paper, film, photographic paper, etc. And due to different types, printing can be presented on a variety of media, such as ordinary offset printing, screen printing, gravure printing, relief printing and so on. , you can print exquisite patterns on paper, plastic, rubber, metal, glass and other materials.
Difference between digital printing and screen printing
1. Substrate and ink
As we all know, screen printing can be described as? General printing? , the adaptability to the substrate is extremely strong, and the tolerance to ink (printing materials) is extremely strong. There is almost nothing that it can't print, and there is almost no ink that it can't miss. However, many digital printing processes have specific requirements for substrates and inks. For example, many printed materials need pretreatment and finishing after printing. The ink used in solvent-based piezoelectric inkjet printers contains more than 50% solvents, but in recent years, due to environmental considerations, traditional inks and coatings are prohibited from using a large number of solvents. It is worth mentioning that UV piezoelectric inkjet is a great progress in digital printing technology. This system can print on various materials, and prepress and prepress materials do not need special treatment, so there is no environmental pollution problem.
2. Impression speed
Digital printing claims to achieve high printing speed, but it is often overlooked that the actual resolution of digital printing is only 36 or 72dpi. If you want to print 720dpi POP, the digital printing speed will slow down by 10~20 times. The speed of screen printing is increased to print a four-color poster every 2 seconds, while it takes more than 15 minutes to spray a poster of the same size. It can be seen that it is almost impossible for digital printing to completely replace screen printing. In addition, the mechanical limitations such as the conversion speed of the print head or the ejection speed of ink droplets also greatly restrict the digital printing technology at some time.
3. Process characteristics
Screen printing has the characteristics of thick ink layer, rich graphic layers, strong three-dimensional sense and extensive printing materials. Screen printing, as a production tool of screen printing art, will not change, and its application in high-grade tobacco and alcohol, food packaging cartons and other emerging fields is gradually increasing. The most prominent advantages of digital printing can be summarized as: one-page printing, no plate making, instant error correction, variable printing and on-demand printing. The different technological characteristics of screen printing and digital printing determine that their applications in the printing market will be different, and it does not conflict who completely replaces them.
* * * Enjoy the difference between printing and network printing.
Briefly summarize the difference between * * * enjoy printing and network printing.
* * * Enjoy the printer is a printer in the local area network, and everyone can use it, but if the computer that enjoys the printer is not turned on, everyone can't use the printer.
The network printer has its own IP, which is equivalent to a computer. As long as the network is open, everyone can use it. Relatively speaking, online typing is more convenient.
People seem to think that online printing means * * * enjoying printing. In fact, online printing is not only enjoyed by * * *, but also developed on the premise that * * * enjoys printing.
Network printing is network printing based on the Internet. The printer is no longer a peripheral, but exists as a contact on the network. It's high-end network printing. The network printer is directly connected to the network adapter card through the EIO slot, which can realize high-speed printing and output at the network speed.
In network printing, management software and print server are juxtaposed as its two core components. Users can remotely browse various printer information, printer settings, usage of toner cartridges, paper status of each carton, etc. The network printing standard also reflects its high reliability, and it is easy to eliminate even if there is a fault, which * * * does not have.
The biggest difference between network printing and * * * enjoy printing is that it has manageability, ease of use and high reliability, and its core is manageability.
